They didn't do 100% checking as it is still leak......................... <_< it is not something mystery. They or you can find it as there are only 3 kinds of water, 1. from radiator(heater system) 2. from outside 3. cool air radiator inside passenger room. Tell them try hard more................... :D

That's right. If no leak of hot water pipes and it has the same water level of radiator you should check front windshield's sealing. I heard someone made claim this part as of assembly defect................... :D

i think you are facing with leak or loose of water drainage pipe of drive's left foot side. you can see pictures here : http://www.fordfocusclub.com/forum/index.php/topic,7090.0.html .................................. :D
